Nagel Precision’s BF-series flexible stone superfinishers are designed to finish inner and outer bearing races. The machines are designed to meet customer specifications and can be equipped with either Siemens or Allen Bradley controls. The ultra-light finishing stone holder is mounted on a servo oscillator and attains speeds as fast as 45 Hz. Coupled servo part drivers are said to reach speeds as fast as 3,000 rpm. Multiple finishing heads can be mounted to achieve a desired quality and output.

Rapid change-over reduces the non-cutting idle time during the machine cycle. The superfinishing heads are mounted on an X and Z axis for automatic positioning and to accommodate part diameter and thickness changes. A part drive system is said to handle a range of part diameters without any change-over.

  • What Is Single Point OD Grinding?

    Two enabling technologies -- superabrasive wheels and high precision servo control -- come together to provide a contour grinding process that resembles an OD turning operation. For many medium volume OD grinding applications, this method may be a means to consolidate several manufacturing steps into a single setup.

    Optimizing a camshaft lobe grinding cycle has traditionally been based less on science and more on educated guesswork and numerous test grinds. Now, computer thermal modeling software can predict areas where lobe burning is likely to occur, in order to determine the fastest possible work speed that won't thermally damage lobes and greatly reduce the number of requisite test grinds.
